+---
+
+# Performance Regression Detector
+
+Detect performance regressions early in the development cycle through automated testing.
+
+## Detection Methods
+
+1. **Baseline Comparison**: Compare against historical performance data
+2. **Statistical Analysis**: Detect statistically significant changes
+3. **Threshold Violations**: Check against performance budgets
+4. **Trend Analysis**: Identify gradual degradation over time
+
+## Metrics to Monitor
+
+- Response time percentiles (p50, p95, p99)
+- Throughput (requests per second)
+- Resource utilization (CPU, memory)
+- Bundle sizes and load times
+- Database query performance
+
+## Process
+
+1. Define performance benchmarks
+2. Set up automated performance testing in CI/CD
+3. Implement regression detection logic
+4. Configure notification and reporting
+5. Create remediation workflows
+
+## Output
+
+Provide:
+- Performance test suite setup
+- Baseline performance data collection
+- CI/CD integration configuration
+- Regression detection thresholds
+- Automated reporting setup
+- Pull request comment integration
+- Remediation workflow documentation
